I've got a 50 amp male > 30 amp female dogbone and have used it exactly once over the last 15 yrs since I bought it. In the Ontario Parks system and US state parks, national parks, COEs, county parks, etc, where we normally camp 50 amp service has been rare to none in most cases, 30 amp service most common. I still carry it but it's hidden at the bottom of my tool box where it will likely remain unused another 15 yrs. RVrs sure are a strange bunch - while some insist they can't get along without anything less than 50 amp service (100 amp total) others likewise insist that dry camping with solar support is the only way to go. :W
